A population of organisms will not evolve if it is in a state of genetic equilibrium, often described by Hardy-Weinberg principles. This occurs when there are no mutations, no gene flow between populations, random mating, a large population size to prevent genetic drift, and no natural selection acting on the traits. In such conditions, allele frequencies remain constant over generations, preventing evolutionary change.

When did the biosphere begin to evolve?
The biosphere is defined as the living organisms on earth. As such, it began to evolve when the first organisms appeared. Currently, this is believed to have happened about 3.5 billion years ago.
How does competition affect the number of organisms?
Competition can reduce the number of organisms by increasing the struggle for resources such as food, water, and shelter. This can lead to greater competition for survival, limiting the population size as only the fittest individuals are able to thrive. Conversely, competition can also drive some organisms to evolve and adapt, increasing the overall population size over time.
What are two ways an organisms joina population and two ways organisms leave a population?
Organisms can join a population through birth (natality) or immigration. Conversely, they can leave a population through death (mortality) or emigration.
How do organs and organ systems evolve and change from simple to more complex organisms?
Through DNA code that tells the cells how to evolve.
What events occurred that allowed single celled organisms to evolve into more complex organisms at the end of the Precambrian time?
the ozone layer began to develop shielding earth from ultraviolet rays, this was hypothesized that these changes allowed species of single celled organisms to evolve into more complexed organisms
Will cats continue to evolve?
Evolution is the change in allele frequency over time in a population of organisms. So, cats will continue to evolve. Organisms evolve, or go extinct. Speciation is another thing.
The smallest unit that can evolve is a?
Is a population. Consider the definition of evolution.Evolution is the change in allele frequency over time in a population of organisms.
The smallest biological until that can evolve over time is?
The smallest biological unit that can evolve over time is an individual organism, typically a unicellular organism like bacteria or archaea. These organisms can undergo genetic mutations and natural selection, leading to the evolution of their populations over generations.
How many organism's might evolve?
all of the organisms can evolve.
Do organisms decide to evolve?
No
What process does organisms evolve through?
Organisms evolve through the process of natural selection, where individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to future generations. This leads to changes in the gene pool of a population over time, resulting in evolution.
What process in Darwin book say what organisms evolve through?
Darwin said that organisms evolve through the process of natural selection.
What types of organisms would a scientist most likely observe to gain an understanding of how populations can evolve?
A scientist studying how populations evolve would most likely observe organisms with short generation times, high reproductive rates, and large population sizes, such as bacteria or fruit flies. These organisms allow researchers to observe multiple generations quickly and see how genetic changes occur over time within a population.
Does the population or organism go through natural selection?
Populations of organisms go through natural selection, not individual organisms. Through natural selection, certain traits that provide a reproductive advantage become more common in a population over time, as organisms with those traits are more likely to survive and reproduce.
Explain why it is incorrect to say that individual organisms evolve?
It is not correct to say that individuals evolved because it is not possible for an individual to change drastically over their own timelife. Species have the faculty to evolve as a whole not as individual organisms.
How do organisms evolve through natural selection?
Organisms evolve through natural selection by the process of differential survival and reproduction of individuals with advantageous traits. Variations exist within a population, and those that are better adapted to their environment are more likely to survive and pass on their genes to the next generation. Over time, these advantageous traits become more common in the population, leading to evolutionary change.
What organisms did humans start to evolve from?
autotrophs
